SPECIFICATION forming part of Letters Patent No. 589,176, dated August .31, 1897.

A plication filed April 12, 1897.

T0 (old whom it may concerw Be it known that I, JOHN C. JUDGE, of Fall River, in the county of Bristol and State of ll/Iassaohusetts,have invented certain newand useful Improvements in Spinning-Frames, of which the following is a description sufficiently full, clear, and exact to enable those which itis most nearly connected to makea'nd use the same. j My invention has relation to spinningframes, and has for its object to provide improved means for automatically holding the rail in its depressed position during the operation of dofling and for automatically releasingthe same when the frame is again set in motion. Y

Of the drawings, Figure 1 is a side elevation showing the parts of a spinning-frame that cooperate with my device, a portion being broken away to show the connection between the retaining-latch and the shippingrod, the latch being shown in its locking position. Fig, 2 is a similar'view showing the latch raised and the ring-rail in the uppermost position which position it occupies while the frame is in operation.

My invention consists,essential-ly,in a, locking device or detent which serves to hold the ring-rail depressed and which is operated directly from the shipping-rod, so that as the frame is stopped or started the ring-rail is respectively locked or released. I need employ but a single detent, and by my arrangement of parts this can be operated from either side or end of the frame.

As shown in the drawings, A represents the framework of the machine, provided with the usual legs or samsons a. The ring-rail b is supported by the usual lifting-rods e, which move in hearings in the fixed rails c and (1. These lifting-rods havea suitable connection at f with arms 9, which are rigidly fastened to the rock-shaft-g. The usual counterbalance-weights h are also secured to these shafts by means of an arm and serve normally-to raise the lifting-rods c and the ring-rail b. Rigidly fastened to the said rock-shafts g are the arms i. These arms 2' have a suitable pivotal connection with the connecting or weight. rod j, which serves to operate all the rockshafts and theirrespective lifting-rods in uni- Serial No. 631,672.

son. I rigidly secure to this connecting-rodj in any suitable manner a block or projection 70 at a suitable distance from one of the samsons a. To the adjacent samson I pivot in any desired manner a latch or detent' Z. Upon a corresponding part of the shipping-rod q I securea block or lugp. This block or lug I connect with the latch or detent l by a cord m or similar connection, which passes over the pulley o. i

The shipping-rod is provided with the usual rod 0", handle 5, the lever-arm 'u, thelatter being suitably connected withthe shipping-rod at v, or any desired means maybe employed for moving the shipping-rod. Instead of connecting the cord m directly with the latch 11 prefer to introduce at the lower end a spiral spring 25, for a purpose to be described hereinafter.

The operation of my device is as follows: Fig. 2 represents the position of the respective parts of the device when the spinningframe is in operation, the shipping-rod being in a. position to keep the driving-pulley in motion and the latch Z being in its raised position. The weights h are free to keep the ring-rail raised, while, of course, allowing the ring-rail to be reciprocated during the operation of the machine. The mechanism for causing this "reciprocation, as well as for driving the spindles, I have not attempted to sh ow, as it forms no part of my invention.

\Vhen it is desired to remove the bobbins,

the lever g is depressed by the foot of the at- .tendant and at the same time the shippingrod g is shifted by hand to the right'until it occupies the position shown in Fig. 1. This causes the connecting-rod j to move toward the left and at the same time allows the; latch Z to fall and engage the block 7r, which should be adjusted to a proper position on the weightrod. The parts will then be in the position shown in Fig. 1, the ring-rail being depressed and being held in position by the detent 7/, the block 70, and the connecting parts.

After the ring-rail has been depressed it is still necessary that the frame should continue its operation a little to secure the needed slack of the yarn before doffing. By introducing the spring 15 between the latch Z and the cord m I am enabled to move the shipping-rod a slight distance to the left without disengaging the latch 1, thereby securing a few extra turns. needed to produce this slack. The spring 25 should be sufficiently yielding to permit this movement of the shipping-rod q and the cord m without disengaging the detent Z, which is held in position by the friction due to the pressure of the blockicagainst the shoulder of the detent, which pressure is caused by the weights h.

After the doffing operation has been performed the operator depresses the lever g sufficiently to move the block it out of engagement with the shoulder of the detent, thus relieving the shoulder of the binding-pressure. The shippingrod is now turned to start the machine. At the same time the latch Z is raised and the ring-rail is left free to rise under the action of the weights h.

It will be noticed that the operation of my device is entirely automatic, as it has connection with the shipping-rod, that it can be operated from any part of the frame, and that it serves its purpose, while at the same time permitting the frame to be started sufficiently to secure the requisite slack of the yarn.

\Vhile I prefer to have the latch or detent engage a projection upon the shipping-rod, it is obvious that if it were made to engage any portion of the mechanism that raises and depresses the ring-rail such a variation would be within the scope of my invention.

Having thus explained the nature of the invention and described a way of constructing and using the same, though without at tempting to set forth all of the forms in which it may be made or all of the modes of its use,

it is declared that what is claimed is 1. In a sp inn-ing-frame the, combination of the shippi-n'grod, of the-weight-rod and of means operated by the shipping-rod for looking the weight-rod against movement.

2. In a spinning-frame, the combination of the shipping-rod, of the Weight-rod provided with a suitable projection, of a latch located to engage the said projection when the ringrail is depressed, and a suitable connect-ion between the shipping-rod and the latch.

3. In a spinning-frame the combination of the shipping-rod, of the weight-rod, of a detent for locking the weight-rod and of a yielding connection between the shipping-rod and the detent.

4. In a spinning-frame the combination of a shipping-rod, of a detent for preventing the movement of the ring-rail, of the cord and of the spring, said eordand spring forming a yielding connection between the shippingrod and the detent.

5. In a spinning-frame the combination with a ring-rail of mechanism for raising and lowering said rail, a detent for preventing the movement of said rail, and a rod extending longitudinally of the frame and having connection with said detent, whereby the detent may be operated from any part of the frame.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 10th day of April A. D. 1807.
